Five weeks after Double Blaze brought its own Tag Team GX headliners to Japan, a smaller, tighter follow-up set landed with a Legendary/Pseudo-Legendary pairing on the cover — and a Trainer card, not a Pokemon, closing out the checklist as its final number.
SM10a GG End (ジージーエンド) released in Japan on April 5, 2019, as an enhanced expansion pack built on top of SM10 Double Blaze. It carries the Sun & Moon era’s Tag Team GX and solo GX mechanics forward with its own focused lineup, headlined by Garchomp & Giratina GX. This guide covers what’s confirmed about the set’s chase cards and checklist, flags where sources disagree on the total card count, and shows what our own Tokyo sealed stock is priced at right now.
GG End’s confirmed chase cards are Garchomp & Giratina GX SR (SM10a 059) and Heatran GX SR (SM10a 055), with Coach Trainer SR (SM10a 062) closing out the set as its final numbered card. A sealed SM10a GG End Booster Box is currently listed at ¥105,000 (~$644). The set’s total card count is disputed between sources — see the breakdown below before you trust any single number.
Prices below are our own in-Tokyo stock listings, re-checked August 13, 2026, converted at approximately ¥163/USD. Card numbers are cited only where confirmed against limitlesstcg’s individual card pages; where a card’s exact number or rarity couldn’t be independently verified, we’ve said so rather than guessing. Pull-rate references in this article are community-reported where noted, not official Pokemon Company data.
What Is SM10a GG End?
GG End is a Sun & Moon-era Japanese expansion, released April 5, 2019 — about five weeks after its parent set, SM10 Double Blaze (released March 1, 2019). Like other “a”-suffixed Japanese releases from this window, it’s an enhanced expansion pack rather than a full numbered set: a smaller, more focused card pool built to extend Double Blaze’s shelf life with its own chase cards rather than a brand-new mechanic.
The set carries forward the Tag Team GX and solo GX cards that defined the broader Sun & Moon series — two Pokemon sharing a single GX attack in the Tag Team cards, and the usual mix of Trainer support and rarity tiers underneath. GG End’s own identity centers on a Legendary/Pseudo-Legendary Tag Team pairing and a small roster of solo GX Pokemon layered around it.
Set Structure: How Many Cards, Really?
limitlesstcg’s database stops at 062 — Coach Trainer, printed as a Secret Rare — card 063 doesn’t return an individual card page there, which makes 062 the last number we could check directly on that source. Bulbapedia’s set list goes further, itemizing secret-tier cards through 069/054 for 69 cards total — a range that lines up with the higher-rarity Trainer reprints referenced elsewhere in this guide.
| Source | Claimed total | What it implies |
|---|---|---|
| limitlesstcg.com card database | 62 cards | Card 062 (Coach Trainer SR) resolves on individual card pages; card 063 does not — a direct, checkable boundary on this source |
| Bulbapedia set list | 69 cards | Itemizes secret-tier cards through 069/054, its own checkable card-by-card boundary |
We’re not going to pick a winner here. limitlesstcg’s card-by-card boundary stops at 062; Bulbapedia’s set list carries the numbering further, through the secret-tier cards up to 069/054 for 69 cards total. Both figures are presented above so you can weigh them yourself — numbers above 062 can’t be cross-checked on limitlesstcg, so confirm the card number from photos before you buy.
The Confirmed Chase Cards
Two cards anchor GG End’s chase lineup, and both check out against individual card pages:
| Card | Number | Rarity |
|---|---|---|
| Heatran GX (ヒードランGX) | SM10a 055 | Secret Rare |
| Garchomp & Giratina GX (ガブリアス&ギラティナGX) | SM10a 059 | Secret Rare |
| Coach Trainer (コーチトレーナー) | SM10a 062 | Secret Rare |
Garchomp & Giratina GX is the Tag Team pairing that anchors the set — a Pseudo-Legendary/Legendary combination in the same mold as the Tag Team pairs that ran through the rest of the Sun & Moon series. Heatran GX runs alongside it as GG End’s solo-GX Secret Rare, at 055 in the same secret-rare tier. Set summaries also reference other headline names for this release — a Raichu & Alolan Raichu GX pairing and a Mawile GX (クチートGX) — but we couldn’t pin down their individual card numbers and rarities against a checkable source this time, so we’ve kept them out of the confirmed table above. See the caution section below for more on that.
Chase Spotlight: Coach Trainer SR (062)
The card closing out GG End’s confirmed checklist isn’t one of the GX Pokemon — it’s Coach Trainer, a Secret Rare at 062, the same final-number slot pattern that showed up on Remix Bout’s Roller Skater SR and other SM-era enhanced expansions. Full art Trainer cards in the Secret Rare tier were a recurring category across this window, valued independently of whichever Pokemon shared the set, and Coach Trainer is GG End’s entry in that category.
Because it sits at the top of the checklist and closes out the confirmed 001–062 run, Coach Trainer is also the card that anchors the 62-card figure in the set-structure debate above — it’s the last number we could directly verify exists.
Cards We Couldn’t Independently Verify
Set summaries for GG End reference a Raichu & Alolan Raichu GX Tag Team pairing and a solo Mawile GX (クチートGX) as part of the broader chase lineup, alongside higher-rarity reprints of three Trainer cards — a Tag Switch item card, a Reset Stamp item card, and a Karate Belt item card. We could not confirm the exact card numbers or rarity tiers for any of these against a checkable primary source during this research pass.
This doesn’t mean these cards don’t exist as described — it means we’re not comfortable quoting a specific number or rarity we haven’t personally verified. If you’re buying a graded or raw copy of any of these names, ask the seller for a clear photo showing the card number before paying a premium, and treat any listing that can’t produce one with extra scrutiny.
Pull Rates: What We Can (and Can’t) Verify
GG End follows the SM-era rarity ladder used across Japan’s enhanced expansion packs: regular numbered cards at common/uncommon/rare, GX Pokemon at their base rarity, and Secret Rare full-art treatments — Heatran GX, Garchomp & Giratina GX, and Coach Trainer — sitting at the top of the confirmed checklist.
We don’t have an official, sourced pull-rate sheet for this set, and we didn’t collect community pull-rate data during this research pass either. If you see a specific “1 in X boxes” figure quoted for GG End elsewhere, treat it as community-reported and unofficial unless it cites the original product insert or an official Pokemon Company release.
How GG End Fits the SM10 Family
GG End sits in the middle of three related Sun & Moon releases that shipped within about eight weeks of each other in the spring of 2019 — SM10 Double Blaze, then SM10a GG End, then SM10b Sky Legend.
| Set | Code | JP release | Confirmed final number |
|---|---|---|---|
| Double Blaze | SM10 | 2019-03-01 | 107 — Red’s Challenge (SR) |
| GG End | SM10a | 2019-04-05 | 062 — Coach Trainer (SR) |
| Sky Legend | SM10b | 2019-04-26 | 062 — Jessie & James (SR) |
Double Blaze’s own chase card is Reshiram & Charizard GX, printed as a Secret Rare across two separate numbers (096 and 097) — a set we cover in full in our SM10 Double Blaze guide, and a sealed SM10 Double Blaze Booster Box is currently listed at ¥102,900 (update: currently sold out — restock requests via Quick Order) in our own Tokyo stock. Three weeks after GG End, Sky Legend closed out the trio with its own Tag Team GX headliner, Moltres & Zapdos & Articuno GX, alongside Jessie & James at the top of its checklist — our SM10b Sky Legend guide covers that set’s own confirmed lineup and its own card-count dispute.

Frequently Asked Questions
What is SM10a GG End and when was it released?
SM10a GG End is a Japanese Sun & Moon-era enhanced expansion pack, released April 5, 2019, about five weeks after its parent set, SM10 Double Blaze (March 1, 2019). It’s built around a Garchomp & Giratina GX Tag Team pairing plus a small solo-GX and Trainer chase lineup.
How many cards are in the SM10a GG End set?
limitlesstcg’s card database runs 001–062, ending with Coach Trainer SR, and doesn’t resolve card 063 on an individual card page. Bulbapedia’s set list itemizes secret-tier cards through 069/054 for 69 cards total. We present both figures rather than committing to one — if a listing cites a number above 062, confirm the card number from photos before you buy.
What is the chase card in SM10a GG End?
Garchomp & Giratina GX (Secret Rare, SM10a 059) and Heatran GX (Secret Rare, SM10a 055) are the confirmed Pokemon chases, with Coach Trainer (Secret Rare, SM10a 062) closing out the checklist as a Trainer-card chase.
Are Raichu & Alolan Raichu GX and Mawile GX in this set?
Set summaries reference both as part of GG End’s broader lineup, but we could not confirm their exact card numbers or rarity tiers against a checkable source during this research pass, so we’ve listed them as unverified rather than guessing at specifics.
How does GG End fit with SM10 Double Blaze and SM10b Sky Legend?
The three sets released within about eight weeks of each other in spring 2019: Double Blaze (March 1), GG End (April 5), and Sky Legend (April 26). Each has its own confirmed chase lineup — Reshiram & Charizard GX, Garchomp & Giratina GX/Heatran GX/Coach Trainer, and Moltres & Zapdos & Articuno GX/Jessie & James, respectively.
